[Focal myositis--an indication for surgery? A case report]

This case report describes focal myositis, a rare inflammatory pseudotumorous disease previously not mentioned in the surgical literature. Most often a single muscle of the upper or lower extremity is affected. Usually the diagnostic process and treatment require a long time. We present a useful diagnostic cascade and a surgical therapy, which allows the histological differentiation between malignant and inflammatory disease. Even after partial resection of the tumor, the prognosis of focal myositis is excellent.
